Cody and Daniel have 10 balls altogether. Cody has 4 more balls than Daniel. Find the number of balls each boy has.
- Daniel
- Cody
Number of balls that Daniel has = 1 u
Number of balls that Cody has = 1 u + 4
Total number of balls
= 1 u + 1 u + 4
= 2 u + 4
2 u + 4 = 10
2 u = 10 - 4 = 6
1 u = 6 ÷ 2 = 3
(a)
Number of balls that Daniel has
= 1 u
= 3
(b)
Number of balls that Cody has
= 1 u + 4
= 3 + 4
= 7
Answer(s): (a) 3; (b) 7
